United States and Ukraine have negotiated a new peace plan revising the original proposal text.
The initial 28-point plan was too favorable to Russia and unacceptable for Ukraine.
The new 19-point draft eliminates some of the more controversial issues for Ukraine.
The initial plan forced Ukraine to concede territories and give up its NATO membership bid.
The new plan seeks to maintain Ukraine's 'full sovereignty'.
Any peace agreement must be communicated to Russia and must be ratified by Moscow.
Conclusion: The negotiation between the United States and Ukraine shows progress, but there remain delicate points to be discussed and agreed upon, and whether the Kremlin accepts the terms is still uncertain.
